1. Run your program from script, and run "cu system"
if exit code is non null,
2. Run from cron script to (ps -eaf |grep your_progr_name) and
call cu if ps does not show it.

The following answer is to check if a certain program you are looking for in step
1 is running. If not, use the cu command to dial out to your pager. I use this
to see if a jab I run every night at a certain time is running.

Use the "man cu" command to look for examples for your particular flavor
of unix.

Try this, below is a simple script to run from your cronjob, 2 parameters are to be passed (if you do not want to pass mesg to your pager or your pager does not support mesg , ignore the checking part). In summary, you just need to pass in your pager number + your mesg.
